Description
Cause
Remedy
TERRA SPIKE
is making knocking noises
The power takeoff shaft speed
is too high at a shallow
working depth.
Reduce the power takeoff
shaft speed
The tines are too long
Check tine lengths
The guide roller arms have too
much play
Secure with side locking
screws
Plastic collar bushings on the
rear roller are worn
Replace bushings
Arm unit buffer worn
Replace buffer

Cracked or porous rubber-
metal rail
Replace rubber-metal rail
The tine holder is hitting the
turf retainer
Check the setting of the Terra
Spike, if necessary reduce the
working depth
Reduce angle of attack
Reduce the power takeoff
shaft speed
Hood clamp fasteners are

"jumps"
or
"seesaws constantly"
Ground is too compact, or too
dry
Stones in the ground.
Reduce the working depth.
Work the ground in stages to

Replace the drive belt.
The drive belt is slipping
Tension the drive belt
Long holes are produced when
working
Soil is too moist.
Wait until the ground
conditions are suitable for
work.
The driving speed may be too
high.
Reduce the driving speed
In the case of small-diameter
tines the grass is pushed
upwards on exit of tines
Soil is too moist.
Long holes are produced when
working
Varying distances between the
holes
PTO stub shaft speed too
great
Reduce the power takeoff
shaft speed
The mounted tines are too
long
Check the length of the tines
and, if necessary, change
them
